Matador Resources Company Reports Fourth Quarter and Full Year 2021 Financial Results and Provides Operational Update

Matador Resources Company (NYSE: MTDR) (“Matador” or the “Company”) today reported financial and operating results for the fourth quarter and full year 2021. A slide presentation summarizing the highlights of Matador’s fourth quarter and full year 2021 earnings release is also included on the Company’s website at www.matadorresources.com on the Events and Presentations page under the Investor Relations tab. In a separate press release issued today, Matador also provided its 2022 operating plan and 2022 market guidance.

Management Summary Comments

Joseph Wm. Foran, Matador’s Founder, Chairman and CEO, commented, “On both our website and the webcast planned for tomorrow’s earnings conference call is a set of six slides identified as ‘Chairman’s Remarks’ (Slides A through F) to add color and detail to my remarks. We invite you to review these slides in conjunction with my comments below, which are intended to provide context for Matador’s outstanding results for the fourth quarter and full year 2021.

“The year 2021 was a tremendous year for Matador, including record total oil and natural gas production of 31.5 million barrels of oil equivalent, record oil and natural gas revenues of $1.7 billion, record net income of $585 million, record earnings per diluted common share of $4.91 and record Adjusted EBITDA of $1.05 billion, among other milestones (see Slide A). San Mateo also had a record year in 2021, including all-time high throughput volumes for natural gas gathering and processing, oil gathering and transportation and water handling, as well as record net income of $113.6 million and record Adjusted EBITDA of $154.3 million. In 2021, both Matador and San Mateo generated free cash flow in all four quarters, and we instituted and then raised our dividend to begin returning additional cash to our shareholders. We also aggressively paid down debt and ended the year with a leverage ratio of 1.1x, the lowest we have achieved since mid-2014. As you will see throughout this earnings release, Matador finished 2021 strong and entered 2022 in the best shape it has ever been, having accomplished all five of its primary goals for 2021—to reduce debt, to increase shareholder returns, to reduce drilling and completions costs per lateral foot, to increase capital efficiency and to achieve record operational results! The Board and I would like to once again acknowledge and express our sincere appreciation to all Matador and San Mateo employees and contractors for their continued strong execution and teamwork, which made these record results possible.

Fourth Quarter 2021 Highlights and Achievements

“The fourth quarter of 2021 was another excellent quarter for Matador yielding strong production and financial results that contributed significantly to our record results for full year 2021. During the fourth quarter, Matador achieved better-than-expected oil, natural gas and total oil equivalent production and record oil and natural gas revenues, net income and Adjusted EBITDA (see Slide B). San Mateo also finished 2021 on a high note, including better-than-expected financial results (see Slide C).

“Net cash provided by operating activities in the fourth quarter was $334.5 million, a 15% sequential increase, leading to fourth quarter 2021 adjusted free cash flow of $119.3 million. This adjusted free cash flow included $11.0 million in performance incentives received by Matador from our midstream joint venture partner, Five Point Energy LLC, for the 11 Boros wells turned to sales and connected to San Mateo during the second half of 2021. Matador repaid $20 million in borrowings outstanding under its reserves based revolving credit facility in the fourth quarter of 2021 and reduced the borrowings outstanding under its reserves-based revolving credit facility to $100 million at December 31, 2021 from $440 million at year-end 2020. Matador expects to repay another $25 million in borrowings outstanding by the end of February 2022, and as a result of these repayments, Matador expects to reduce the borrowings outstanding under the reserves-based revolving credit facility to $75 million, a reduction of $400 million, when compared to $475 million at the end of the third quarter of 2020. Matador’s leverage ratio under the reserves-based revolving credit facility declined to 1.1x at year-end 2021, a significant reduction from 2.9x at year-end 2020, and, again, marking Matador’s lowest leverage ratio since mid-2014 (see Slide D).

Key 2021 Milestones Achieved, Along with Record Capital Efficiency

“Matador’s 2021 priorities and milestones are summarized in Slide E, and we executed very well on this operating and capital efficiency plan throughout 2021. During the fourth quarter of 2021, we achieved our final key operational milestone when we turned to sales nine new wells in our Greater Stebbins Area in December. Overall, we believe Matador’s 2021 operating program was a tremendous success and made significant progress in all these areas. Drilling and completion costs averaged $670 per completed lateral foot for 2021, an all-time low on an annual basis, and a year-over-year decrease of 21% from $850 per completed lateral foot in 2020, our previous all-time low (see Slide F). During 2021, Matador turned to sales 47 gross (44.2 net) operated horizontal wells in the Delaware Basin with an average lateral length of approximately 10,500 feet, all but one of which had a lateral length of two miles or longer. Notably, these 47 wells, in aggregate, including the costs of the nine new Greater Stebbins Area wells we turned to sales in December, had already achieved payout by the end of the year. Obviously, these wells should continue to provide Matador with strong operating cash flows for many years to come.

2022 Operating Plan and Market Guidance

“Finally, in conjunction with this earnings release, we have also released today our 2022 operating plan and market guidance. As you will see in that companion release, we believe that 2022 should again be exciting for Matador and all of its stakeholders, as we continue developing our excellent Delaware Basin assets, generating significant free cash flow, paying down debt, evaluating potentially accretive acquisition opportunities and returning cash to shareholders through increases to the dividend as our performance allows. The Matador staff in both the office and in the field are growing in teamwork, expertise and experience and are due the credit for generating these results. We expect to have record production results again in 2022 and should oil and natural gas prices continue to remain strong throughout 2022, we believe our 2022 operating plan, in the capable hands of our office and field staff, should generate record financial results and cash flows as well, while generating substantial value growth for all our stakeholders in the year ahead and for years to come.”

Fourth Quarter 2021 Operational and Financial Highlights

Net Cash Provided by Operating Activities and Adjusted Free Cash Flow

• Fourth quarter 2021 net cash provided by operating activities was $334.5 million (GAAP basis), leading to fourth quarter 2021 adjusted free cash flow (a non-GAAP financial measure) of $119.3 million.

Net Income, Earnings Per Share and Adjusted EBITDA

• Fourth quarter 2021 net income (GAAP basis) was $214.8 million, or net income of $1.80 per diluted common share, a sequential increase from net income of $203.6 million in the third quarter of 2021, and a significant year-over-year increase from a net loss of $89.5 million in the fourth quarter of 2020.

• Fourth quarter 2021 adjusted net income (a non-GAAP financial measure) was $151.2 million, or adjusted net income of $1.26 per diluted common share, a sequential increase from adjusted net income of $148.6 million in the third quarter of 2021, and a significant year-over-year increase from adjusted net income of $32.3 million in the fourth quarter of 2020.

• Fourth quarter 2021 adjusted earnings before interest expense, income taxes, depletion, depreciation and amortization and certain other items (“Adjusted EBITDA,” a non-GAAP financial measure) were $299.1 million, a sequential increase from $293.8 million in the third quarter of 2021, and a year-over-year increase from $150.1 million in the fourth quarter of 2020.

Oil, Natural Gas and Oil Equivalent Production

As summarized in the table below, Matador’s fourth quarter 2021 average daily oil, natural gas and total oil equivalent production were all above the Company’s expectations. The majority of the higher-than-expected production resulted from the timing of shut-in operations in the Stateline asset area associated with hydraulic fracturing operations on the 11 Voni wells. The Company did not begin hydraulic fracturing operations on these 11 wells until the second week of November, as opposed to on November 1, allowing for approximately ten additional days of full production from the Stateline asset area prior to a significant number of these wells being shut in for the 11 Voni well completions as planned.

Capital Expenditures Below Expectations; Drilling and Completions Costs Per Foot In-Line

• Matador incurred capital expenditures for drilling, completing and equipping wells (“D/C/E capital expenditures”) of approximately $166 million in the fourth quarter of 2021, or 18% below the Company’s estimate of $202 million for D/C/E capital expenditures during the quarter. Matador estimates that approximately $15 million of these savings were directly attributable to continued improvement in operational efficiencies, while the remainder of the savings resulted primarily from the timing of both operated and non-operated drilling and completion activities, and most of these costs are currently expected to be incurred in the first quarter of 2022.

• For full year 2021, Matador’s D/C/E capital expenditures were approximately $513 million, or about 7% below the midpoint of Matador’s updated guidance of $550 million for full year 2021 D/C/E capital expenditures, as provided on October 26, 2021. These annual cost savings were achieved despite the increasing service cost inflation experienced in the second half of 2021 and despite pulling forward the most recent 11 Voni well completions into the fourth quarter of 2021.

• Drilling and completion costs for all operated horizontal wells turned to sales in the fourth quarter of 2021 averaged approximately $738 per completed lateral foot, a sequential increase of 14% from average drilling and completion costs of approximately $650 per completed lateral foot in the third quarter of 2021 and in-line with the Company’s expectations for the fourth quarter. This increase was primarily attributable to the inflation in oilfield service costs associated with drilling and, in particular, completion operations, a trend that the Company expects to continue throughout 2022.

• For full year 2021, drilling and completion costs for all operated horizontal wells turned to sales averaged approximately $670 per completed lateral foot, a year-over-year decrease of 21% from average drilling and completion costs of $850 per completed lateral foot achieved in full year 2020.

Total Borrowings Continue to Decline

• At December 31, 2021, Matador’s leverage ratio, as defined in the Company’s reserves-based credit facility, was 1.1x, which was better than the Company’s expectations for year-end 2021. The leverage ratio of 1.1x marks Matador’s lowest leverage ratio since mid-2014. At December 31, 2021, total borrowings outstanding under Matador’s reserves-based credit facility were $100 million, a reduction of $20 million from total borrowings outstanding of $120 million at September 30, 2021.

• Matador expects to repay an additional $25 million in borrowings outstanding under the reserves-based credit facility before the end of February 2022. Total borrowings outstanding under the reserves-based credit facility at February 28, 2022 are expected to be $75 million.

Reserves-Based Credit Agreement Amended and Restated

• On November 18, 2021, Matador announced the closing of a new amended and restated credit agreement (the “Credit Agreement”). Under the Credit Agreement signed on November 18, 2021, (i) the maturity date was extended by three years to October 31, 2026, from October 31, 2023 previously; (ii) the borrowing base was increased by 50% to $1.35 billion, as compared to $900 million previously; (iii) the elected borrowing commitment was reaffirmed at $700 million; and (iv) the maximum facility amount was reaffirmed at $1.5 billion. Matador also added three new banks to its lending group under the Credit Agreement.

• Additional details regarding the new Credit Agreement were provided in the Company’s November 18, 2021 press release, and additional financial terms and covenants under the Credit Agreement were included in the Form 8-K filed with the U.S. Securities and Exchange Commission.

Credit Rating and Senior Notes Upgraded by S&P

• On January 27, 2022, as previously announced, S&P Global Ratings (“S&P”) upgraded Matador’s issuer credit rating from ‘B’ to ‘B+’ and upgraded Matador’s issue-level rating on Matador’s senior unsecured notes from ‘B+’ to ‘BB-’.

Note: All references to Matador’s net income (loss), adjusted net income (loss), Adjusted EBITDA and adjusted free cash flow reported throughout this earnings release are those values attributable to Matador Resources Company shareholders after giving effect to any net income (loss), Adjusted EBITDA or adjusted free cash flow, respectively, attributable to third-party non-controlling interests, including in San Mateo Midstream, LLC (“San Mateo”). Matador owns 51% of San Mateo. For a definition of adjusted net income (loss), adjusted earnings (loss) per diluted common share, Adjusted EBITDA, adjusted free cash flow and PV-10 and reconciliations of such non-GAAP financial metrics to their comparable GAAP metrics, please see “Supplemental Non-GAAP Financial Measures” below.

Sequential and year-over-year quarterly comparisons of selected financial and operating items are shown in the following table:

Recent Acquisitions and Divestitures

Acquisitions – Delaware Basin, Lea and Eddy Counties, New Mexico and Loving County, Texas

During the second half of 2021 and through February 22, 2022, Matador acquired both producing and non-producing properties in the Delaware Basin in Lea and Eddy Counties, New Mexico and Loving County, Texas as a result of both asset purchases and organic leasing activities for a total consideration of approximately $242 million, inclusive of customary purchase price adjustments, and did so without increasing total debt outstanding or the leverage ratio at year-end 2021. The majority of these properties are located between the Company’s Mallon and Rodney Robinson leasehold positions in Lea County, New Mexico, and a large portion of the acreage acquired includes “bolt-on” positions to the Company’s existing acreage in the western portion of its Ranger asset area. These properties also include a variety of smaller tracts acquired in several of the Company’s Delaware Basin asset areas in both New Mexico and Texas.

Approximately $217 million associated with these transactions was paid by Matador during the third and fourth quarters of 2021, which is reflected in the Company’s full year 2021 cash flow statements provided with this earnings release. The Company paid an additional $25 million upon closing the remaining properties associated with these transactions during January and February 2022. Matador has funded these acquisitions using free cash flow from its operations generated during the second half of 2021 and the first quarter of 2022.

Additional details regarding the acquired properties include the following:

• Approximately 3,750 BOE per day at the time of the various acquisitions, including flush production from three new wells turned to sales in November 2021, and for which Matador realized only about 50,000 BOE as part of its fourth quarter 2021 total production, or less than 1% of its fourth quarter 2021 total production, as a result of acquiring these properties late in the fourth quarter;

• Approximately 22,400 gross (12,700 net) acres acquired, including a mix of fee, state and federal acreage;

• Approximately 206 gross (128.6 net) locations identified for future drilling, including prospective targets throughout the Wolfcamp, Bone Spring and Avalon intervals; and

• Production characterized by higher oil cut wells (70% or greater) and lower water production (water-oil ratios typically three-to-one or less).

Matador expects to add approximately 16.6 million BOE, including 12.1 million barrels of oil and 26.5 billion cubic feet of natural gas, associated with these properties to its estimated total proved oil and natural gas reserves, a portion of which was included in the Company’s proved oil and natural gas reserves at December 31, 2021 and the remainder of which will be included in the Company’s proved reserves as of March 31, 2022. The Standardized Measure and PV-10 (present value discounted at 10%, a non-GAAP financial measure) of these proved oil and natural gas reserves are approximately $186.1 million and $227.1 million, respectively, using an oil price of $63.04 per barrel and a natural gas price of $3.60 per MMBtu, which were the prices used to value the Company’s proved reserves at December 31, 2021. Matador expects to add future proved reserves, Standardized Measure and PV-10 as a result of the development of these properties going forward.

At February 22, 2022, Matador has contracted a sixth drilling rig to begin development of certain of these properties in Lea County, New Mexico. Matador expects to turn to sales seven gross (5.9 net) wells associated with these properties in 2022, all of which are anticipated to be turned to sales late in the fourth quarter.

Divestitures – Eagle Ford Shale, South Texas

Between September 2021 and January 2022, Matador divested approximately 9,800 gross (9,300 net) acres in Dewitt and Zavala Counties, Texas and received proceeds of approximately $14.3 million. At the time of these divestitures, the Company had minimal production and proved developed reserves attributable to these properties. Matador also had no proved undeveloped reserves attributable to these properties at the time of these divestitures.

Operations Update

Drilling and Completion Activity

Matador operated five drilling rigs in the Delaware Basin during the fourth quarter of 2021 as planned, and the Company expects to operate these five drilling rigs throughout its various asset areas in the Delaware Basin throughout 2022. In addition, at February 22, 2022, Matador had contracted a sixth operated drilling rig to begin drilling operations immediately on recently acquired acreage in western Lea County, New Mexico in Matador’s Ranger asset area (please see Recent Acquisitions and Divestitures discussion above). Matador expects to operate this sixth operated rig on the newly acquired acreage throughout the remainder of 2022. Accounting for the anticipated impact of service cost inflation in 2022, the six-rig drilling program results in only a small increase to the Company’s expected 2022 D/C/E capital expenditures, as compared to the four-rig drilling program Matador conducted for the majority of 2021, primarily as a result of lower working interests associated with many of the wells Matador expects to drill and complete in 2022. Additional details regarding Matador’s 2022 operating plans are provided in the Company’s 2022 Operating Plan and Market Guidance press release issued separately today.

Wells Completed and Turned to Sales

During the fourth quarter of 2021, Matador turned to sales a total of 39 gross (9.3 net) wells in its various operating areas as shown in the table below. This total was comprised of nine gross (8.0 net) operated wells and 30 gross (1.3 net) non-operated wells. All operated wells were two-mile laterals. The two gross (1.4 net) wells in the Ranger asset area originally scheduled to be turned to sales in late December were turned to sales in mid-January 2022. For full year 2021, Matador turned to sales 104 gross (48.2 net) wells in its various operating areas, including 47 gross (44.2 net) operated wells and 57 gross (4.0 net) non-operated wells.

Greater Stebbins Area

In December 2021, Matador turned to sales nine gross (8.0 net) wells in the southern portion of its Arrowhead asset area (the “Greater Stebbins Area”), all of which were two-mile laterals, including four Third Bone Spring, four Wolfcamp A-XY and one Wolfcamp B completion. The initial results from these wells were comparable to previous wells completed in these formations in the Greater Stebbins Area, with most wells exhibiting approximately 70% oil cut. As is customary for wells completed in this area, most of these wells are being equipped with artificial lift, some with gas lift and some with electrical submersible pumps (ESPs), and, as a result, several of these wells were shut-in during portions of the first quarter of 2022 pending the completion of these artificial lift operations. All nine of these wells are expected to be returned to production by the end of the first quarter.

Overall, Matador is quite pleased with its 13-well drilling program in the Greater Stebbins Area during 2021, which also included four gross (3.5 net) Second Bone Spring wells turned to sales in the third quarter of 2021. At February 22, 2022, these 13 wells are expected to achieve an average payout time of approximately 1.5 years, where payout is defined as net oil and natural gas revenues received less D/C/E capital expenditures and all associated operating expenses incurred since the wells were turned to sales. At February 22, 2022, these 13 wells are also projected to deliver a return on invested capital of approximately three-to-one, where invested capital is defined as all D/C/E capital expenditures incurred, based on long-term average commodity prices of $65 per barrel for oil and $3.00 per MMBtu for natural gas. Matador looks forward to resuming drilling operations in the Greater Stebbins Area in mid-to-late 2022.

Stateline Asset Area

During the fourth quarter of 2021, Matador was completing 11 new Voni wells on the western side of its Stateline asset area, and as a result, the Company did not turn to sales any wells in the Stateline asset area during the fourth quarter. At February 22, 2022, the 11 new Voni wells, including five Third Bone Spring completions, four Wolfcamp B completions and two First Bone Spring completions have been turned to sales as anticipated. In addition, most of the wells shut in during the fourth quarter of 2021 in the Stateline asset area have now been returned to production. Four Boros wells, which were not originally anticipated to be shut-in during the first quarter of 2022, have been shut in for most of the first quarter, however, to protect these wells during completion operations by an offset operator immediately east of the Stateline asset area. Matador anticipates these wells will be returned to production before the end of the first quarter of 2022.

Overall, Matador is extremely pleased with the results from the 26 Stateline wells turned to sales during 2021. These 26 wells were turned to sales at various times during the year, primarily during April and September 2021, and most of these wells achieved, or are expected to achieve, payout in six months or less. Drilling and completion costs averaged $628 per completed lateral foot, the lowest that Matador has achieved to date in any of its asset areas. The 26 wells in the Stateline asset area turned to sales during 2021 achieved payout, in aggregate, in October 2021, and at February 22, 2022, these wells are projected to deliver a return on invested capital of greater than six-to-one, based on long-term average commodity prices of $65 per barrel for oil and $3.00 per MMBtu for natural gas!

Realized Commodity Prices

Oil Prices

Matador’s weighted average realized oil price, excluding derivatives, was $76.82 per barrel in the fourth quarter of 2021, a 10% sequential increase from $69.73 per barrel in the third quarter of 2021, and an 87% year-over-year increase from $40.99 per barrel in the fourth quarter of 2020. Matador’s weighted average oil price differential relative to the West Texas Intermediate (“WTI”) benchmark, inclusive of the monthly roll and transportation costs, was ($0.43) per barrel in the fourth quarter of 2021, as compared to ($0.79) per barrel in the third quarter of 2021 and ($1.71) per barrel in the fourth quarter of 2020.

For the first quarter of 2022, Matador’s weighted average oil price differential relative to the WTI benchmark price, inclusive of the monthly roll and transportation costs, is anticipated to be in the range of $0.00 to ($1.00) per barrel.

At February 22, 2022, Matador had approximately 5.1 million barrels of oil hedged for full year 2022, or about 25% of its anticipated 2022 oil production, using costless collars with a weighted average floor price of approximately $60 per barrel and a weighted average ceiling price of approximately $83 per barrel. Please see the accompanying presentation for a more complete summary of Matador’s current oil derivatives positions.

Natural Gas Prices

Matador’s weighted average realized natural gas price, excluding derivatives, was $7.68 per thousand cubic feet in the fourth quarter of 2021, a 22% sequential increase from $6.27 per thousand cubic feet in the third quarter of 2021, and a 2.6-fold increase from $2.97 per thousand cubic feet in the fourth quarter of 2020. NGL prices, and especially propane prices, continued to be strong in the fourth quarter, which contributed to the Company’s weighted average natural gas price being above the Company’s expectations in the fourth quarter of 2021. For the fourth quarter of 2021, Matador’s weighted average natural gas price differential relative to the Henry Hub benchmark price was +$2.86 per thousand cubic feet, as compared to +$1.95 per thousand cubic feet in the third quarter of 2021 and +$0.21 per thousand cubic feet in the fourth quarter of 2020. Matador is a two-stream reporter, and the revenues associated with its NGL production are included in the weighted average realized natural gas price.

For the first quarter of 2022, Matador’s weighted average natural gas price differential relative to the Henry Hub benchmark price is anticipated to be positive in the range of +$2.00 to +$2.50 per thousand cubic feet, primarily attributable to improved natural gas price differentials at the Waha hub in West Texas, assuming NGL prices continue to remain strong throughout the first quarter.

At February 22, 2022, Matador had approximately 54.7 billion cubic feet of natural gas hedged for full year 2022, or about 55 to 60% of its anticipated 2022 natural gas production, using costless collars with a weighted average floor price of approximately $3.07 per MMBtu and a weighted average ceiling price of approximately $5.81 per MMBtu. Please see the accompanying presentation for a more complete summary of Matador’s current natural gas derivatives positions.

Operating Expenses

On a unit of production basis:

• Production taxes, transportation and processing expenses increased 10% sequentially from $5.90 per BOE in the third quarter of 2021 to $6.48 per BOE in the fourth quarter of 2021. This increase was primarily attributable to increased production taxes associated with oil and natural gas revenues of $510.8 million, an all-time quarterly high, reported by Matador in the fourth quarter.

• Lease operating expenses remained relatively flat sequentially at $3.34 per BOE in the fourth quarter of 2021, as compared to $3.31 per BOE in the third quarter of 2021. Lease operating expenses decreased 9% year-over-year from $3.81 per BOE for the year ended December 31, 2020 to $3.46 per BOE for the year ended December 31, 2021, marking the lowest annual lease operating expenses on a unit of production basis in the Company’s history.

• General and administrative expenses increased 6% sequentially from $2.97 per BOE in the third quarter of 2021 to $3.14 per BOE in the fourth quarter of 2021. General and administrative expenses in the fourth quarter reflected the reinstatement of employee compensation beginning in March 2021, which had been previously reduced by the Board and staff in March 2020 in response to the significantly lower oil and natural gas price environment at that time. The increase also reflects increased year-end bonus payments made to Matador’s employees in 2021. No bonuses were awarded to Matador management and staff in 2020.

San Mateo Highlights and Update

Operating Highlights and Financial Results

San Mateo operations in the fourth quarter of 2021 were highlighted by better-than-expected operating and financial results. Operationally, water handling volumes were at an all-time high of 313,000 barrels per day, a 10% sequential increase from the third quarter of 2021, and natural gas gathering and processing volumes were both up about 2% sequentially during the fourth quarter as well. Fourth quarter 2021 volumes do not include the full quantity of volumes that would have otherwise been delivered by certain San Mateo customers subject to minimum volume commitments (although partial deliveries were made in the fourth quarter), but for which San Mateo recognized revenues during the fourth quarter of 2021.

Operating Highlights

During the fourth quarter of 2021, San Mateo:

• Gathered an average of 252 million cubic feet of natural gas per day, a 2% sequential increase, as compared to 248 million cubic feet per day in the third quarter of 2021, and a 17% year-over-year increase, as compared to 216 million cubic feet per day in the fourth quarter of 2020.

• Processed an average of 236 million cubic feet of natural gas per day at the Black River Processing Plant, a 2% sequential increase, as compared to 232 million cubic feet per day in the third quarter of 2021, and a 35% year-over-year increase, as compared to 175 million cubic feet per day in the fourth quarter of 2020.

• Gathered and transported an average of 41,800 barrels of oil per day, a 2% decrease, as compared to 42,500 barrels per day in both the third quarter of 2021 and the fourth quarter of 2020.

• Handled an average of 313,000 barrels of produced water per day, a 10% sequential increase, as compared to 284,000 barrels per day in the third quarter of 2021, and a 20% year-over-year increase, as compared to 260,000 barrels per day in the fourth quarter of 2020.

Financial Results

During the fourth quarter of 2021, San Mateo achieved record financial results, including:

• Net income (GAAP basis) of $33.6 million, a 14% sequential increase from $29.5 million in the third quarter of 2021, and a 28% year-over-year increase from $26.2 million in the fourth quarter of 2020. This quarterly result was a record high for San Mateo and above the Company’s expectations for the fourth quarter, primarily resulting from stronger-than-expected throughput volumes.

• Adjusted EBITDA (a non-GAAP financial measure) of $43.6 million, a 7% sequential increase from $40.8 million in the third quarter of 2021, and a 23% year-over-year increase from $35.4 million in the fourth quarter of 2020. This quarterly result was a record high for San Mateo and above the Company’s expectations for the fourth quarter for the reasons noted above.

• Net cash provided by San Mateo operating activities (GAAP basis) of $33.1 million, leading to San Mateo adjusted free cash flow (a non-GAAP financial measure) of $28.9 million.

• In early 2022, San Mateo repaid $30 million in borrowings outstanding under its credit facility. Total borrowings outstanding under the San Mateo credit facility at February 22, 2022 were $355 million. The San Mateo credit facility is non-recourse with respect to Matador.

For the year ended December 31, 2021, San Mateo also achieved record financial results, including:

• Net income (GAAP basis) of $113.6 million, a 40% sequential increase from $80.9 million for full year 2020.

• Adjusted EBITDA (a non-GAAP financial measure) of $154.3 million, a 37% sequential increase from $112.7 million for full year 2020.

• Net cash provided by San Mateo operating activities (GAAP basis) of $143.7 million, leading to San Mateo adjusted free cash flow (a non-GAAP financial measure) of $87.0 million.

Matador’s portion of San Mateo’s capital expenditures was approximately $7 million in the fourth quarter of 2021, about $9 million less than the Company’s estimate of $16 million for the fourth quarter, primarily attributable to both cost savings on completed projects and the timing of operations. For full year 2021, Matador’s portion of San Mateo’s capital expenditures was approximately $31 million, or about 23% below the midpoint of Matador’s guidance of $40 million for its portion of San Mateo’s full year 2021 capital expenditures.

Environmental, Social and Governance (“ESG”) Update

Matador is committed to creating long-term value for its stakeholders in a responsible manner by pursuing sound growth and earnings objectives and exercising prudence in the use of its assets and resources. During 2021, Matador continued its efforts to highlight the Company’s commitment to ESG excellence. In May 2021, Matador published sustainability metrics aligned with standards developed by the Sustainability Accounting Standards Board (“SASB”), and in July 2021, Matador published an update providing supplemental information to the Company’s initial report on these SASB-aligned ESG metrics.

In December 2021, Matador was pleased to issue its inaugural Sustainability Report in an effort to further raise the profile of Matador’s ongoing ESG-related initiatives. This report highlights Matador’s continued progress and improvements in its operating practices, including the quantitative metrics aligned with the SASB standards noted above, and should provide Matador’s stakeholders and interested parties with a standardized platform for evaluating the Company’s recent performance and future progress. Matador’s inaugural Sustainability Report, including the SASB-aligned sustainability metrics, is available on the Company’s website at www.matadorresources.com/sustainability.

Matador is also pleased to report today on its continued commitment to safety throughout its operations. Once again, Matador incurred no employee lost time incidents during approximately 600,000 employee man-hours in 2021. The Company has not incurred a recordable employee injury since 2014, and, over the last five years, from 2017 through 2021, Matador has incurred no employee lost time incidents during approximately 2.7 million employee man-hours. Matador gratefully acknowledges the conscientious efforts of its Environmental, Health and Safety team and of the experienced field and office staff involved in the Company’s drilling, completions, production and midstream operations to proactively minimize environmental hazards and safety risks, address any potential areas of concern and continuously emphasize Matador’s “safety first” culture.

Supplemental Non-GAAP Financial Measures

Adjusted EBITDA

This press release includes the non-GAAP financial measure of Adjusted EBITDA. Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external users of the Company’s consolidated financial statements, such as securities analysts, investors, lenders and rating agencies. “GAAP” means Generally Accepted Accounting Principles in the United States of America. The Company believes Adjusted EBITDA helps it evaluate its operating performance and compare its results of operations from period to period without regard to its financing methods or capital structure. The Company defines, on a consolidated basis and for San Mateo, Adjusted EBITDA as earnings before interest expense, income taxes, depletion, depreciation and amortization, accretion of asset retirement obligations, property impairments, unrealized derivative gains and losses, certain other non-cash items and non-cash stock-based compensation expense and net gain or loss on asset sales and impairment. Adjusted EBITDA is not a measure of net income (loss), or net cash provided by operating activities as determined by GAAP. All references to Matador’s Adjusted EBITDA are those values attributable to Matador Resources Company shareholders after giving effect to Adjusted EBITDA attributable to third-party non-controlling interests, including in San Mateo.

Adjusted EBITDA should not be considered an alternative to, or more meaningful than, net income (loss) or net cash provided by operating activities as determined in accordance with GAAP or as an indicator of the Company’s operating performance or liquidity. Certain items excluded from Adjusted EBITDA are significant components of understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure. Adjusted EBITDA may not be comparable to similarly titled measures of another company because all companies may not calculate Adjusted EBITDA in the same manner. The following table presents the calculation of Adjusted EBITDA and the reconciliation of Adjusted EBITDA to the GAAP financial measures of net income (loss) and net cash provided by operating activities, respectively, that are of a historical nature. Where references are pro forma, forward-looking, preliminary or prospective in nature, and not based on historical fact, the table does not provide a reconciliation. The Company could not provide such reconciliation without undue hardship because such Adjusted EBITDA numbers are estimations, approximations and/or ranges. In addition, it would be difficult for the Company to present a detailed reconciliation on account of many unknown variables for the reconciling items, including future income taxes, full-cost ceiling impairments, unrealized gains or losses on derivatives and gains or losses on asset sales and impairment. For the same reasons, the Company is unable to address the probable significance of the unavailable information, which could be material to future results.

Adjusted Net Income and Adjusted Earnings Per Diluted Common Share

This press release includes the non-GAAP financial measures of adjusted net income and adjusted earnings per diluted common share. These non-GAAP items are measured as net income (loss) attributable to Matador Resources Company shareholders, adjusted for dollar and per share impact of certain items, including unrealized gains or losses on derivatives, the impact of full cost-ceiling impairment charges, if any, and non-recurring transaction costs for certain acquisitions or other non-recurring expense items, along with the related tax effect for all periods. This non-GAAP financial information is provided as additional information for investors and is not in accordance with, or an alternative to, GAAP financial measures. Additionally, these non-GAAP financial measures may be different than similar measures used by other companies. The Company believes the presentation of adjusted net income and adjusted earnings per diluted common share provides useful information to investors, as it provides them an additional relevant comparison of the Company’s performance across periods and to the performance of the Company’s peers. In addition, these non-GAAP financial measures reflect adjustments for items of income and expense that are often excluded by industry analysts and other users of the Company’s financial statements in evaluating the Company’s performance. The table below reconciles adjusted net income and adjusted earnings per diluted common share to their most directly comparable GAAP measure of net income (loss) attributable to Matador Resources Company shareholders.

Adjusted Free Cash Flow

This press release includes the non-GAAP financial measure of adjusted free cash flow. This non-GAAP item is measured, on a consolidated basis for the Company and for San Mateo, as net cash provided by operating activities, adjusted for changes in working capital and cash performance incentives that are not included as operating cash flows, less cash flows used for capital expenditures, adjusted for changes in capital accruals. On a consolidated basis, these numbers are also adjusted for the cash flows related to non-controlling interest in subsidiaries that represent cash flows not attributable to Matador shareholders. Adjusted free cash flow should not be considered an alternative to, or more meaningful than, net cash provided by operating activities as determined in accordance with GAAP or an indicator of the Company’s liquidity. Adjusted free cash flow is used by the Company, securities analysts and investors as an indicator of the Company’s ability to manage its operating cash flow, internally fund its D/C/E capital expenditures, pay dividends and service or incur additional debt, without regard to the timing of settlement of either operating assets and liabilities or accounts payable related to capital expenditures. Additionally, this non-GAAP financial measure may be different than similar measures used by other companies. The Company believes the presentation of adjusted free cash flow provides useful information to investors, as it provides them an additional relevant comparison of the Company’s performance, sources and uses of capital associated with its operations across periods and to the performance of the Company’s peers. In addition, this non-GAAP financial measure reflects adjustments for items of cash flows that are often excluded by securities analysts and other users of the Company’s financial statements in evaluating the Company’s cash spend.

The table below reconciles adjusted free cash flow to its most directly comparable GAAP measure of net cash provided by operating activities. All references to Matador’s adjusted free cash flow are those values attributable to Matador shareholders after giving effect to adjusted free cash flow attributable to third-party non-controlling interests, including in San Mateo.
